Scientists from Argentina's national health agency have deployed a network of traps throughout Ushuaia, the southern port city that serves as the main entry point to Antarctica, to determine whether a rat‑borne hantavirus sparked the recent outbreak on the MV Hondius cruise ship.. The operation, carried out in protective gear, involves collecting dead rodents and extracting blood samples for laboratory testing.

Traps placed across Ushuaia to trace MV Hondius outbreak

According to the field report , teams positioned traps at multiple locations around Ushuaia, including the harbor, residential districts, and waste‑handling sites, aiming to map the distribution of rodent carriers. The strategic placement reflects the city's role as a logistical hub for Antarctic voyages, where cargo and passenger traffic could inadvertently transport disease vectors.

Dead rats bagged for makeshift lab analysis

Collected rodents are being sealed in black plastic bags and loaded onto pickup trucks that double as a temporary laboratory , where technicians will draw blood to test for hantavirus antibodies. The makeshift setup underscores the urgency of the investigation, as officials seek to confirm whether the virus is present in an area previously thought to be free of rodent‑borne hantavirus strains.

Scientists decline comment as investigation proceeds

When approached for remarks, the scientists involved in the project did not provide comments to journalists, leaving details of the sampling methodology and timeline undisclosed.. This silence fuels speculation about the potential scale of the rodent infestation and the likelihood of further human cases.

Echoes of past South American hantavirus scares

Health officials note that hantavirus outbreaks have periodically emerged in Argentina’s northern provinces, where agricultural workers are most at risk. The current focus on Ushuaia marks a geographic shift,prompting comparisons to earlier incidents that prompted large‑scale rodent control campaigns in the 1990s.

Who will verify the lab results?

The report indicates that blood samples will be sent to a national virology institute for confirmation,but the timeline for results remains unclear. As the MV Hondius remains docked for passenger quarantine, authorities are awaiting definitive lab data to decide whether additional public health measures are required.
